Thelgaug shw ts-a w BEST AVAILABLE COPY ate the valve, the handle F is moved. This moves the actuating part F so as to bring it into contact with the valve stem D The valve stem is then moved to one side and f: the valve D tilted as shown in dotted lines in Fig. 1. This opens the passageway C and permits the escape of the water from the chamber E. The pressure in said chamber being thus relieved the pressure in the chamber E causes the diaphragm B to be moved away from the cylinder C carrying with it the piston O, the movement in this case being preferably rapid. When this movement of the piston is rapid, a small amount of I water will escape when the groove C is opposite the upper edge of the cylinder C but it will be only a comparatively small amount. The parts are arranged so that when the diaphragm is up its maximum distance, the groove C will be above the top of the cylinder C When in this position the valve stem D is above the actuating part F and out of the influence thereof, and j the force of gravity moves it back to its closed position so that the valve D will be properly seated. This closes the communication leading from the chamber E. The

chamber begins then to gradually fill up 3 with water, the water passing from the chamber E through the openings A to chamber E. The diaphragm is now gradually moved toward the end of the cylinder C When the groove comes opposite the upper edge of said cylinder the water will flow therethrough down into the pipe F and thus to the closet or other device in connection with which the water is used. When theinclined, part C of this groove is passin v the end of the-cylinder C it will be note that'the space is gradually decreased, and hence the flow of water is gradually shut oil, the parts being arranged so that the last fiow of water acts as a re-fill to re-fill the basin. It will thus be seen that the flush and re fill are both accomplished by means of the same groove in the piston. WVhen the diaphragm reaches the position shown jinijl the communication between the 'gpipej FFahd chamber E will be cut off, and fithe flow of water stopped. When it is deto again operate the valve, the handle be moved to one side and the operation above described will be repeated. noted that by this construction athereis liti'close adjustment required of the or ofthe auxiliary valve D.

The piston and diaphragm and associated parts stop automatically when the valve stem rises above the actuating. part. The parts are so arranged that when the diaphragm and piston are u the groove 0 is above the end of the cylinder C and the flow of water is stopped. It, now, the actuating part should be held in its actuating position the end of the valve stem D will strike it. The end of the valve stem is preferably rounded and the actuating part may also be rounded so that when the end of the valve stem strikes it the valve will be tilted and hence the further downward movement of the piston stopped because of the escape of the water from chamber E. This willresult before the groove C comes opposite the upper end of the cylinder C and hence it will be impossible to hold the valve open. Means are provided'for adjusting the'flow of water from the chamber E to the chamber E through the passage way:A This may be done, for example, by means ofthe adjusting screw Aflwhich can be'worked back and forth across the mouth of the passage way A To insure making this connection water tight, 1 preferably provide the jamnut B which can be constructed'to carry the bumper B for the seat. The central position of the handle is not essential under all circumstances as it would be possible to locate the handle in another relaparatus.
